WoT armor angling calc

EA = Effective armor against ammo that have no normalization (HE/HESH/HEAT).AP = Armor against AP/APCR/APDS rounds, that have 5° normalization.

To find the armor values for AP/APCR/APDS rounds you will use the same formula above,
but only subtract the 5° normalization value off of the highest angle. Therefore, if a
piece of armor is angled at 45° vertically and 30° horizontally then you will only add
the normalization change to the 45° angle since it is the highest. (Source)
